LUMBER-LOADING JACK.

SPECIFICATION forming part of Letters Patent No. 503,335, dated August 15, 1893. Application filed November 12, 1892. Serial No. 451,723. (No model.)

To all whom t 11mg/ concern:

Be it known that I, EDGAR L. STocKrNe, a citizen of the United States, residing at Buffalo, in the county of Erie and State ot' New York, have invented new and useful Improvements in Lumber- Loading Jacks, of which the following is a specification.

This invention relates to the supports or jacks which are used in connection with freight cars for loading the same with lumber from a Wagon or pile adjacent to the car.

The object of my invention is the provision of a simple device of this kind, whereby the transfer of the lumber from the wagon or pile into the car is facilitated, and which can be conveniently adjusted vertically onthe car, as the same becomes filled.

In the accompanying drawings:--Figure l is a perspective view of a railway car provided with my improved lumber jack. Fig. 2 is a fragmentary transverse section thereof. Fig. 3 is a fragmentary horizontal section of the saine in line 3-3, Fig. 2, the sliding roller, the swinging rest moved inwardly, and the board resting upon the same being represented in dotted lines.

Like letters of reference refer to like parts in the several iigures.

A is the door opening in the side of the car and B the usual sliding door.

C is the removable supporting roller which is commonly placed across the door opening and over which the lumber is rolled into the car.

D is an upright supporting bar or standard arranged on one side of the door opening and removably attached to the car by any suitable means, so that the same can be removed when no longer required. The standard is preferably provided at its upper end with a serrated hook CZ which embeds itself in the car roof, and its lower end is coniined in a loop c arranged on a bracket E which is clamped to the under side of the car frame by a screw c. This clamping screw engages in a threaded opening formed in a raised lip e2 arranged at the inner end of the bracket, as shown in Fig. 2.

F is a horizontally swinging rest 0r lumberjack pivoted to the standard D and upon which the boards are supported in swinging them into the proper position, preparatory to shoving them into the car. The lumberjack F consists of an upper horizontal arm upon which the boards rest, and a lower inclined arm or brace F. These arms terminate at their inner ends respectively, in pivots ff, which are iitted loosely in suitable eyes or brackets attached to the standard, so as to permit the jack to swing freely toward and from the door opening of the car and advance with the board resting thereon as the same is shoved into the car. The upper pivot of the swinging rest is arranged outward beyond its lower pivot or in a different vertical plane and its pivot eyes are arranged in correspondingly differentplanes, as shown in Figs. l and 2. By this arrangement the rest when unrestrained swings automatically into a position at right angles to the side of the car, or nearly so, when moved out of that position.

Several sets of pivot eyes or brackets g g' g2 are preferably arranged on the standard D in a vertical series, so that the swinging rest may be adjusted vertically on the standard by placing its pivot in a higher or lower set of eyes. Each intermediate bracket g is provided with an outer eye or opening g3 and an inner eye g4. The upper brackets g are each formed with a single eye arranged in line with the outer eyes of the intermediate brackets, and the lower brackets are each formed with a single eye arranged in line with the inner eyes of the intermediate brackets, as shown in Figs. l and 2. The several brackets are so spaced that the eyes of any two alternate brackets will receive the pivots of the swinging rest. By constructing the intermediate brackets g' with two eyes, as shown, they are capable of supporting either the upper or the lower pivot of the rest according to its elevation. The rest is readily detached from the standard for raising or lowering it, by simply lifting it sufficiently to disconnect its pivots from the eyes of the supporting brackets.

In loading a car with the aid of my improved jack, the board is raised at its front end from the wagon or lumber pile and placed with its middle portion upon the swinging rest. Its front end is then depressed to raise its rear end and the board isthen pushed rearwardly which causes the pivoted rest to swing inwardly toward the car opening, and the rear IOO end of the board to ride over the roller C and enter the car as shown by dotted lines in Fig.

3. The board is now lifted from the rest and shoved entirely into the car. The rest being relieved from the weight of the board automatically swings outward to its former posi-v tion, as before described, ready to receive and carry the next board into the ear. In beginning to load the car the pivoted rest is supported in the uppermost set of eyes and as the pile of lumber on the wagon is lowered the rest is correspondingly lowered. As the boards are carried toward and into the car opening by the freely swinging rest, which follows the rearward movement of the boards, the latter are introduced into the car with comparatively little effort, thus greatly facilitating the loading of the car.

I claim as my inventionl. The combination with the standard, of a horizontal lumber rest having upper and lower l pivots whereby it is journaled to said standard, the upper pivot of the rest being offset or arranged in adiiferent vertical `plane from the lower pivot, whereby the rest is caused to return automatically to its initial position when released by the removal of the lumber, sub-- stantially as set forth.

2. The combination with the standard, of a2 number of sets of stationaryeyes or brackets y arranged at different elevations on the standard, and a vertically adjustable lumber restr having upper and lower pivots detachably seated in said eyes, substantially as set forth.

3. The combination with the standard, of a 'vertical series of stationary brackets arranged on the standard and each having inner and outer openings or eyes arranged at different distances fromxthe standard, and a horizontally swinging lumber rest having upper and lower pivots, arranged ont of a vertical line with each other, the inner one of said pivots being adapted to engage in the inner opening of one of said brackets, and the outer pivotin the outer openin g of another of said brackets, substantially as set forth.

4. The combination with the standard, of one or more upper brackets arranged on the standard and each having an eye, one or more lower brackets also arranged on said standard and each having an eye arranged inwardly beyoud-said upper eyes, intermediate brackets each having an outer eye arranged in line with the eyes of said upper Ybrackets and an inner eye arranged in line with said lowerbrackets,

lower pivots which engage with a set of said eyes, substantially as set forth.

- and a swinging lumber-resthaving upper and f 5. In a lumberjack, the combination with a f removable standard provided at its upper end with a hook for engaging the roof of a car, of a bracket for coniining the lower end of the standard consisting of a horizontal bar provided at its outer end with a loop which embraces the standard, and at its inner end with an angular lip, and a clamping screw vpassing through said lip bearing against the car frame or body and a lumber rest attached to the standard, substantially as set forth.

Witness my hand this Sth day of November, 1892.
